"What is a variable?
A variable is used in a Fair Test. A variable is any one of the elements of the test which could be changed. They can change the outcome of an experiment.
In a fair test, only one variable is allowed to be manipulated – all others have to be kept the same,or “controlled”."

Answer:
1. 145-(3squared times 4)=109
2. 45 divided by 9 times 12-8= 52
3. 2 squared +3 times 4-12= 4
4.[155-(3 times 9) times 2] -12= 89
5. [(6 times 2) +(5 times 5) times 3= 111
6. 2 times {15+[24-(1.5 times 2)]}= 72
Step-by-step explanation:
(BOMDAS) brackets, operations, multiplication, division, addition, subtraction
1. (deal with the brackets first)
3 squared=9 then times by 4 =9*4=36
so..
145-36=109
2. (start with division )
45 divided by 9 =5
so
5 times 12-8= 52
3. 2 squared = 4
4 times 3 =12
so
4+12-12 =4
4. (deal with brackets first)
3 times 9 = 27
27 times 2= 54
155-54= 101
101-12=89
5. (deal with the brackets first)
6 times 2 =12
5 times 5=25
so 12+25= 37 times 3 = 111
6. (deal with the brackets first)
1.5 times 2= 3
24-3= 21
15+21=36
2 times 36= 72

Answer:
18 1/12 ft = base length
Step-by-step explanation:
The area of a triangle of base b and height h is A = (1/2)(b)(h).
Since we want the measure of the base we solve this formula for b:
2A = (b)(h)
2A
and then divide both sides to obtain a formula for b: b = -----------
h
Substituting 217 ft^2 for A and 24 ft for h, we get:
b = 2*217 ft^2 / 24 ft = 18.0833.... ft
If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction. One way of doing this is to use a calculator. On my old TI calculator, I would type in 0.0833333333..
and then press the MATH key and then select Option 1: Decimal to fraction.
Doing this yields 1/12. You can check this result by dividing: 1/12 = 0.08333...
Then the final answer, converted from 18.08333... ft, is
18 1/12 ft = base length

Answer:
it is 3
Step-by-step explanation:
cause 3 is the highest exponent value
Answer:
The degree of this polynomial is 3.
Step-by-step explanation:
Hey!
==================================================================
When a polynomial has more than one variable, we need to look at each term to find out what the degree is. Terms are separated by + or - signs.
Find the degree by adding the exponents of each variable in it,
The largest such degree is the degree of the polynomial.
Let's start out by finding the degrees for each terms:
3x³ = The degree, or exponent, of x is 3.
5x² = The degree, or exponent, of x is 2.
1 = Constant Terms do not have a degree.
So, since the largest degree of a term is the degree of the polynomial., The degree of this polynomial is 3, since that is the highest!
==================================================================

Part of the population of 5,750 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 10 of them are infected. How many elk are likely to be infected?
Based on the sample, there will likely be infected elk in the wildlife preserve. List the next 4 multiples of the fraction 5/6
Answer:
575
Step-by-step explanation:
If a sample of 50 is selected and ten out of that are infected, dividing you would get my answer. To get it, divide the sample amount that were infected by the whole amount. I am unsure if this is correct but fingers crossed this helps. Feel free to talk it through with me.

Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why? (1 point) a (−3, −5), because the point satisfies one of the equations b (−3, −5), because the point lies between the two axes c (−4, −8), because the point satisfies both equations d (−4, −8), because the point does not lie on any axis
Answer:
The answer is "C"
Step-by-step explanation:
Answer:
Answer C. This point lies between the two axes and its coordinates satisfy both equations
Step-by-step explanation:
Line A: y = x − 4
Line B: y = 3x + 4
Let's actually solve this system, using substitution: Equate
Line A: y = x − 4 to Line B: y = 3x + 4, obtaining:
x − 4 = 3x + 4
Subtract (x - 4) from both sides. Doing so yields
0 = 2x + 8, and so x = -4.
From Line A let's find y: Letting x = -4, we get: y = -4 - 4 = -8
and so the solution is (-4, -8). This matches Answer C. This point lies between the two axes and its coordinates satisfy both equations.
Solve: -x + 4 = -9 and -3x + 7 = 1

Answer:
27 Degrees
Step-by-step explanation:
Since 63 and x make 90 degrees, 90-63 is 27 which gives you the answer. The equation is X=90-63.
Answer:
63 + x = 90
Step-by-step explanation:
The desired equation is 63 + x = 90, because the angles 63 and x are complementary (they add up to 90 degrees).

Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14

Answer:
144 ft^2
Step-by-step explanation:
Here we have a trapezoid with a triangle inside.
The legs of the trapezoid are 18 ft and 8 ft, and so the average length of the trapezoid is (18 + 8)/2 ft, o 13 ft. The total area of the trapezoid is thus:
A = (13 ft)(16 ft) = 208 ft^2
Now we must find the area of the white triangle and subtract it from the area of the trapezoid already found. The area formula for a triangle i
A = (1/2)(base)(height), which in this case is A = (1/2)(8 ft)(16 ft), or
A = 64 ft^2.
Subtracting the area of the triangle from that of the trapezoid yields
Area of figure = 144 ft^2
A triangle has one angle that measures 26 degrees, one angle that measures 47 degrees, and one angle that measures 107 degrees.
What kind of triangle is it?
A triangle has one angle that measures 34 degrees, one angle that measures 47 degrees, and one angle that measures 99 degrees.
What kind of triangle is it?
A.
equilateral triangle
B.
scalene triangle
C.
right triangle
D.
isosceles triangle
Answer: Scalene
Step-by-step explanation:
None of the angles equals the other so no isosceles or equilateral and a right triangle had a right angle and all right angles equal 90 degrees.

Write a real world problem in which you need to find the volume of a right rectangular prism. Solve your problem.
Answer:
Tiffany just got an aquarium for her rare turtle. She wants to fill it with water but it came without the volume measurement on it. She measures and finds aquarium's length is 30 inches, width is 12 inches, and height is 18 inches. How many cubic inches of water does she need?
Step-by-step explanation:
The formula for right rectangular prism is Length×Width×Height
30×12×18 = 6480
So she needs 6,480 in³ of water
In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 16, 18, 18, 24, 25, 27, 28, 31, 31, and 32. Jean made the qualitative statement, "The average weight of the raccoon population is 26 pounds." Is her statement reasonable? Complete the explanation.
Jean's statement (select) reasonable because the median value of the data is pounds.
Answer:
The average is 24 so her answer is reasonable cause it is not too far off.
Step-by-step explanation:
Average = sum/count
(16 + 18 + 18 + 24 + 25 + 27 + 28 + 31 + 31 + 32)/10
240/10
24
24 is close to 26
